President Donald Trump visited Saudi Arabia over the weekend, and the oil-rich kingdom pulled out all the stops.

Saudi Arabia was the first stop on Trump's weeklong trip abroad, the first of his presidency. He traveled to Israel on Monday, with stops in Vatican City, Belgium, and Italy scheduled over the next week.

American country music star Toby Keith hosted a concert in Riyadh on Saturday night, and Trump "did a slow roll" in a golf cart past a livestream of the event with his wife Melania and Saudi King Salman bin Abdulaziz. Women weren't allowed at the concert.

Trump, al-Sisi, and Salman placed their hands on a glowing orb to officially open the Global Center for Combating Extremist Ideology and start a welcome video Sunday night. Twitter lit up with jokes comparing the photo to science fiction villains.
